    At jlcpcb.com a 8.43" * 10.436" five boards is 23.10USD, with chamfered edges and ENIG 44.60USD. Shipping depends on your country for CH its about 20USD. No I don't think individual boards are that expensive.

    I understand there is a learning curve between point to point projects and making your own boards. I was at the same point before I started to make my own boards. But the result with individual boards is much more satisfying.

    Sorry, ENIG is not a comparable or appropriate surface finish for card edges if you intend for the board to last. A layer of gold a few atoms thick won't stand up to a single insertion with high contact forces, and then you're left with nickel. "Extra heavy ENIG" as advertised by some cheap Chinese board shops is not actually a real thing -- ENIG works on ion swap, once the nickel layer is covered, no more swaps, no more plating.

    It's not a question of being bad at laying out circuit boards, which seems to be what you're hinting at. It's a preference in making one-offs, and on valuing what we're doing with our time as hobbyists. Deciding what's "more satisfying" is entirely a personal opinion, too.
